In making certain types ofupholstered VVJfurniture or in vmaking similar upholstered parts in quantity itis desirable notbnlyv thatsuiicient pressure be applied; to 'the' part which is upholstered, but also that'ltliis Ypressure be substantially." uniform, in order to make the 4upholstered parts: ofbfuniiorm quality. The present invention is 'designed c and -intended not'only for applying vthe l power by'means of a motor, butAV also. by

' providing a weighing attachment, insures that `the 'same' or a substantially uniform pressure `may be applied to similar or f all of the upholstered piecesgf ff Q1 A In'carrying out this' invention a depending y or Y ceiling support` 5 has av depending i yoke 6 attached thereto'in which the shaft .7;'is movablely TheV upper endo the' shaft l is provided with; a' threaded portion. 3,V and vu() attachedto the 'lower-'end Whichprojects be-4 yond..the yoke iswan upholsterngggheadr) shown` in a diagrammatic or informal VWay asapplied lto a piece 10 to be upholstered supported byan upliolsteringfbench or table le5, 11;H In the opposite edgesof'the shaft are -Zmilled grooves 12 and 13 attached to .be enf ,Y Y Y,"gaged by the roller contact-arms'lll and 15.
